Whether you’re whipping up fried chicken, delicious onion rings or fries, a commercial deep fryer is a massive asset to any establishment.
Unfortunately, it can get messy when used daily. You can keep these units running in peak condition by doing some routine commercial kitchen maintenance throughout the week.
So what exactly do you need to do? Below are helpful tips and instructions for how to clean a commercial fryer.
Over time, fat and carbon deposits will build up on your fryer’s heating element and in the tank. We recommend cleaning this weekly, but you should always stick to your machine’s manufacturer’s advice if there is doubt. Check your owner’s manual for specific instructions for boiling out your fryer, or follow the general suggestions below:
Turn off the fryer and let the oil inside cool.
Once the oil cools down, drain it from the machine into a heatproof container.
Using a fryer brush rod or scraper remove the oil and buildup from the walls and base.
Fill the fryer with water up to the level line. Add 150g of Ceres Deep Fryer Cleaner per 10 litres of water.
Turn on the fryer and let the water and Ceres Deep Fryer Cleaner solution boil for 20 minutes. This will help remove excess grease remaining in the machine.
Turn the unit off and allow the water to cool down significantly. Once it’s cool enough, discard it in a heatproof container.
Wipe off the bottom and side walls using a sponge, cloth or paper towel. Mix warm water and Ceres Deep Fryer Cleaner in a bowl or bucket. Using a soft-bristle brush or a clean non-abrasive sponge, scrub down areas of the interior where oil and other remnants are still present.
Rinse the interior with warm water to remove the soapy mixture and oil remnants.
Aside from boiling out the machine and cleaning its exterior, try these preventative maintenance tricks for your commercial deep fryer.
Monitor for Leaks
Even if you don’t smell them, try to check for gas leaks every month or so. Spray the gas-conducting hoses with a soap-based cleaner and watch for bubbles. If gas is leaking out of the lines, the soap will bubble up. If this happens, you should immediately shut off the gas and contact a technician to help you correct the issue.
Your fryer can also fall victim to grease leaks. These are less dangerous and they’re also easier to spot. However, they’re still a risk. If you notice a puddle of grease, make sure to take prompt steps to fix any hoses or parts where the leaks are coming from.
This is just a fancy way of saying “don’t get extra stuff in your oil” like excess food or water. Foreign objects in your oil will speed its breakdown, causing the taste to deteriorate more quickly. Of course, this is unavoidable to a certain extent, but you can take steps to guard against it. Load your fry baskets away from the fryer so that loose particles of food and ice crystals don’t end up in the oil. Maintaining the purity of your cooking oil will keep it lasting longer.
Optimise Oil Quality & Lifespan
You can further protect and prolong the lifespan of your fryer oil by keeping the heat relatively low. We suggest maintaining a temperature of under 180°C and decreasing the temperature to 120°C during downtime.
Make sure you place a cover on your fryer at night or during any extended period during the day when it’s not in use. Just like any food product exposed to air, your oil can become stale. Use a fryer oil filter to remove foreign matter that finds its way into the oil.
